Comet C/2023 A3, also known as Tsuchinshan-ATLAS, is making a rare and breathtaking return to Earth’s skies after an astonishing 80,000-year journey around the Sun. From Friday through Monday, early risers will have the unique opportunity to catch a glimpse of this celestial wonder in the early morning sky.
According to BBC Sky at Night Magazine, Comet C/2023 A3 completes its orbit every 80,000 years, making this an extraordinarily rare event for stargazers. The comet is expected to become a prominent object in the morning sky by late September 2024, shining brightly at a magnitude of +0.6 just before sunrise. The comet will reach its closest point to the Sun, known as perihelion, on September 28, 2024. As it ascends into the evening sky around October 10, observers can anticipate slightly dimmer views, with the comet predicted to shine at a magnitude of +0.8.
NASA astronaut Matthew Dominick, currently stationed aboard the International Space Station, shared a mesmerizing video of the comet on social media. In his post, he described the comet as appearing like “a fuzzy star” when viewed with the naked eye from the ISS’s cupola windows. However, using a 200mm f/2 lens with a 1/8s exposure, Dominick captured more detailed images, showcasing the comet’s potential for stunning visuals as it draws closer to the Sun.
Amateur astronomer Stuart Atkinson from Cumbria also provided insights into what viewers can expect. He noted on social media that the comet would resemble “a fuzzy star with a misty tail” positioned low in the eastern sky beneath the Moon. Atkinson suggested that using binoculars could enhance the viewing experience, offering a more detailed look at this once-in-a-lifetime celestial event.
Don’t miss the chance to witness this extraordinary astronomical phenomenon as Comet C/2023 A3 graces our skies for the first time in millennia.
